4 is what percent of 3.31 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 3.31 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 3.31, so we can write it down as 100%=3.31.
4. We know, that x% equals 4 of the output value, so we can write it down as x%=4.
5. Now we have two simple equations:
1) 100%=3.31
2) x%=4
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=3.31/4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4 is what percent of 3.31

100%/x%=3.31/4
(100/x)*x=(3.31/4)*x       - we multiply both sides of the equation by x
100=0.8275*x       - we divide both sides of the equation by (0.8275) to get x
100/0.8275=x
120.84592145015=x
x=120.84592145015

now we have:
4 is 120.84592145015% of 3.31
